We’re a wasteful nation, with householders throwing away around 7 million tonnes of food and drink a year – that’s 5kg per household, every week. We always try to avoid unnecessary waste in the Good Food Test Kitchen and here’s how we go about it...


Stop wasting food

1. Protect your potatoes

Good storage is everything with potatoes – it can more than double their lifespan. Store in a cool, dark place, ideally between 5C-8C, but not in the fridge. The best place is a cool pantry or shed. Place the potatoes in a paper bag or hessian sack, to allow the moisture to escape, and keep them in the dark, preventing them from sprouting or rotting. They will keep for up to a month.

2. Don't buy bags of salad

These deteriorate very quickly once opened, so buy whole heads of lettuce instead; they’ll last much longer. If you want loose-leaf, opt for watercress, rocket & spinach medleys, which can be whizzed into pesto and frozen at the first sign of wilting.

3. Make dairy last longer

Freeze milk that is nearing its use-by date in manageable one-pint portions, then defrost when needed. Grate leftover scraps of cheese into a plastic container (mixed varieties are fine) and freeze. Use straight from the tub for scattering over lasagne or pizza. Mix natural yogurt with crushed berries or mashed bananas, then freeze in ice lolly moulds for a lower-fat alternative to ice cream.

4. Keep bread better

If your family rarely gets through a whole loaf of bread before it turns mouldy, stash half the loaf in the freezer, in two-slice portions, as soon as you buy it. Bread defrosts in minutes, or pop straight into the toaster if you have a defrost function. Alternatively, stale bread is great for breadcrumbs, bread & butter pudding or a panzanella salad.

5. Use up apples

If your apples have that week-old powdery texture, grate into porridge, boil peeled chunks with potato to mash and serve with sausages, or make into apple sauce or compote and stash in the freezer.

Be a savvy shopper

6. Buy whole cuts of meat for sandwiches

You’ll spend way over the odds for packets of pre-sliced ham, chicken or beef. Instead, pick up a joint of gammon, silverside or rump of beef, a whole chicken or a turkey breast. Cook yourself, then slice and freeze in individual portions. Defrost the night before you make your sarnies.

7. Head to the market

Fresh produce at farmer's market

Fruit and veg can be expensive in supermarkets. Instead, visit your local market, where it is often half the price – especially at the end of the day, when the stallholders are anxious to shift it.

8. Visit the bakery

Most supermarket bakeries bake fresh bread in-house every day. They often stock fresh wraps and naan bread, which – aside from tasting better than the long-life ones available with ready-made Mexican and Indian ingredients – are usually much cheaper. If you’re not going to use them all within a few days, stick leftovers in the freezer to have on standby for a curry or fajita night.

9. Don't squander expensive oils

If the flavour of the oil will be lost in the dish, don’t use expensive olive or rapeseed oil. Fill a glass bottle with regular vegetable oil – which will look much nicer on your kitchen counter – and use this instead.

Get organised in your kitchen

10. Sort out your cupboards

A well-stocked storecupboard will help you to bulk out leftovers for quick weeknight suppers, and save you money. To prevent cans and jars at the back hanging around past their use-by date, stock like they do in the supermarket – bring the oldest items to the front and slip your new ones in the back. Save your best, more expensive oils for salad dressings and drizzling over finished dishes.

11. Empty your freezer

Don’t let your freezer become a graveyard of chicken bones and fish fingers. While most items will be safe to eat for a few months, it’s best to use up food while it’s as fresh as possible – or before you completely forget what that brown ice block in the sandwich bag is! Once a month, try to have a week of meals from the freezer to have a good clear-out.

12. Cut down on ready meals

These are usually expensive, often nutritionally unbalanced, and never as good as homemade. Instead of spending money on one of the most wasted foods in the UK, spend some time at the weekend making a batch of stew, chilli or curry. Freeze in individual portions, ready for when you need a speedy meal. Look out for the freezable symbols on our recipes.
